In the drawings, the jack comprises a pair of standards 1 and 2 which are inclined toward each other and are of suitable height; said standards consist of angle-iron uprights 3 which converge toward their upper ends and have their lower ends connected and braced by the angle-iron sills 4 which are adapted to rest on the ground, as best seen in Fig. 4 of the drawings. The upper ends of the uprights 3 of each standard are preferably spaced apart for a suitable distance and are connected and braced by the short studs 5 as shown; and the upper ends of the corresponding uprights 3 of the standards 1 and 2 are connected, braced and suitably held spaced apart by means of the angleiron braces or sills 6, as shown.

The braces or sills G extend parallel with each other and are held suitably spaced apart and braced by means of the studs 7 which are silni to those indicated .as 5, bracin the upper ends of the uprights 3 of each 0? the standards, and said studs 7 not only serve to brace and hold the sills 6 suitably spaced apart but connect them as one piece to adapt the braces or sills 6 to be detached at their opposite ends from the upper ends of the uprights 3 at the standards 1 and 2. To the opposite ends of said braces or sills 6 and between the same are journaled the grooved pulleys or rollers 8 and t); the former having a double groove to adapt two parts of a rope or cable to ride over the same and the latter being prefer ably provided with only one roove to allow one portion of a rope or cable to ride over the same. Spindles 1O carry the grooved pulleys or rollers 8 and 9 and saidspindles have a bearing in the braces or sills 6, and when said braces or sills are connected up with theuprights 3 of the standards 1 and 2, the said spindles are dro v ped into and extend through slots 11 in he upper ends of the uprights 3, which form a bearing for the outer ends of said spindles. In such position the horizontal portions of the angle- .iron braces or sills 6 will rest on the upper ends mfthe uprights 3, as best seen in Figs. 1, 2 and 7. The braces or sills G are braced from the body of the upri hts 3 by means of the straps or reaches 12 w iich are pivotally connected to the uprights 3 'as shown in Figs. 4 and 7, and the upper ends of said straps or reaches 12 are slotted as at 13, see Fig. 7, to allow the same to have a detachable connection with shoulder rivets 14 secared to and projecting inwardly from the inneixfaces of the braces or sills 6. Thus, it will be en, that the straps or reaches 12, through t ,provision of the slots 18 in their upper ends, be disconnected from the rivets 14, abov referred to, by swinging said reaches 12 upward and outward, which will release the braces or sills 6 from the standards 3, when said braces or sills 6 may be lifted or detached from the standards, leaving the jack in three distinct parts, con sistingo'l the stand rds 1, 2 and the braces or sills (3, which are connected with each other in the manner specified.

The uprights 3 of each standard are braced from each other by means of the straps 15 connected at their opposite ends to the opposite upright 3, as best seen in Fig. 4;

and overlying the pulleys 8 and 9 are straps 16 which are connected to the opposite braces 6, in the manner best seen in Figs. 1 2 and isl with said shaft, a drum 19 to which is attached a large gear wheel 20, which latter may be securedto the shaft 18 if it is so desired in lieu of the drum 19. Centrally of this drum is secured the looped end 21 of a rope or cable 22, the opposite ends of which being indicated as 23 and24 are carried up andover the pulley heretofore indicated as 8, the end of said ro e or cable 23 extending across the top of said jack and over the pulley 9, the end 24- passlng down and around the pulley 8, and said ends 23 and 24 are adapted to be passed through the front.

wheels B of a wagon which is here indicated as A, and looped and secured about the hubs of said wheels, so that. when the drum shaft 18 is operated for the purpose of Winding the said rope or cable 22 about thedrum 19, the front of said wagon will be elevated somewhat in the nianner seen in Fig. 4 of the drawings. The manner of o crating the drum shaft'will now be described.

25 denotesa driving shaft, the opposite ends of which pass through and are 'ournaled in boxings 26, secured to the uprights of the standard 1, and the opposite ends of the said driving shaft are squared to allow for the connection therewith of a power shaft which is, shown in dotted lines in Fig. 4 and indicated as 27; this shaft is adapted to have a suitable connection with some suitable source of power for operating the mechanism for raising the said wagon. Jacks for the purposes herein are known to the trade and several different forms of power appliances are in use, any one of which may be used. To the opposite end of the power shaft 25 may be connected a tumbling rod shown in dotted lines in Fig. 4 and indicated as 28, which said tumbling rod is desi nod to have a suitable connection with an elevator to which is connected a other drag or cross conveyor for receivingthe material as it is discharged from the rear end able connection with the shaft 25 is a clutch part 31 having a clutch face"32 adapted to engage with the clutch face 30 of the pinion 29 for connecting the said pinion withthe por'er shaft when it is desired to transmit,

from the power shaftto the drum motion shaft 18. For transmitting such motion I haveprovided an intermediate orcounter' shaft 33 which is disposed hetweenthe power shaft 25 and the drum shaft 18 and journaled at its opposite ends in boxings 34 securedtothe uprights 3 on the standard 1. On such shaft is a. large gear wheel 35 which meshes with the pinion- 29 on the power shaft, and

there i also provided on said intermediate orcounter shaft a pinion 36 which meshes" with the gear wheel 20 on the drum shaft 18. Thus, it will be seen hat when the power shaft 25 is in motionfand the' clutch 31 is thrown into engagement with the pin-1 ion 29, motion will be imparted iiomv the power shaft through the p nion 29 andthe gear 35 to the interme iate or counter shaft 83 and from the counter shaft through the pinion 36 to the gear 20, which will impart motion to the drum shaft 18 and'the drum shaft inturn through the drum thereon and its connection with the rope or cable 22,1-

will, if the ends of said'cable are secured to the elevate the front end of the said wagon such operation being continued until the clutch 31 is disconnected from the pinion 29. I have provided in connection with such raising mechanism means, clutch may from thejpinion 29 when the front end of the w gfin reaches a predeterminedheight or sai clutch may lie manually disengaged from said pinionwvlfenever the, operator sov desires such disconnec ion. And I have provided that when the clutch 31 is re leased or disengaged from the pinion 29,

the mechanism may be locked forretaining the wagon in such elevated position until.

the operator again desires that the same shall be lowered, when, tlielocking m'eans will he released and the wagon allowed to drop by gravity, at the same time the operator has control of such movement and may stop the wagon at will, all ofwhichwill explainedmore fully in detail.

WlVhen the operator throws the bur er rod 4-? to the left (looking-at Fig. 1), he will,

through. the connection of therod 41. wih the bar'39 throw the lever .37 also to the le t. which will cause the'cln'tch 31 to engageas' ith the pinion? 29 and slightly raise the nner end of said bar 39. This will cause the rope or cable to hewound onthe' druin 19' and will elevate tte frontend of a wagon intheman nor hereinbeforejstated, and when "the wagon has reached a p'redeterminedlieight, which is governed by the position of the collar 47 on the end 24'of the rope or cable 22,"said' collar will engage with the end of and forcing :it downwardly. will' shift or throw the lever '37' into the position shown in 1 Fig. 1. and cause the separation ofthe clutch face 32'of theclntch '31 from the clutch part "30 of the -pinion"29 :an'd check the upward 'movementof the said wagon. I

Lwill now describe the mechanism for thehar 39 locking the gearing which is employed for raising the wagon, so as toretain the wagon in such elevated pos ion until the operator determines that he desires to again lower the said wagon. On the intermediate or -rounter shaft 33 is carried a smoothed face pulley or drum 48, which may be connected directly with said shaft or formed a part of the gear wheel 35, and carried around or encircling the periphery of said pulley or drum 48 is a strap or band 49, one end of which is secured about the drum shaft 18 and the opposite end thereof is secured at 50 to a lever 51, said lever having the short right angular portion 52 to which is pivotally connected a-rod 53, the outer end of which is preferably reduced and passes through the portion of the strap or band 49, which extends up and is secured about the drum shaft 18, and on the outer reduced end of said rod are secured nuts 54 forretaining a connection between the rod 53 and the strap or band 49. To the outer free end of the lever 51 is connected :1 rod 55 which has its 0 posite' end connected with one end of a ever 56 which is fulcrumed at 57 to one of the uprights 3 of the standard 1. The upper end of the lever 56 is positioned in proximity to and at the rear of the bar or rod 42 and said bar or rod has secured thereto a rod 58, see Fig. 3, the outer end of which is ada ted, when the said bar or rod 42 is projected forwardly for the purpose of causing the clutch 31 to engage with the pinion 29, to engage with the upper end of the lever 56 and oscillate it to the right, looking at Fig. 3, which said movement will raise the outer end of the lever 51 and move the rod 53 to the right, looking at Fig. 5, which will release the cable on the drum for the purpose of elevat-- ing thewagon in the manner hereinbefore stated. Upon the collar 47 on the rope or cable engaging with the outer end of the bar, 39, which operates to automatically move t e lever 37 to release the clutch parts,

or shot! (1 the operator desire to release the gearing which he would do throu h the shiftin of'the operator's rod 40 an by it move he lever 37. the bar or rod 42 will move into a direction just opposite to that above described, moving the end of the rod 58 from the lever 56 and permittinga' coil spring 59 connected at one end to the lever 51 and at its opposite end to a frame part 60 secured to one of the uprights 3,'to draw the lever 51 down into its normal position,-

and by such movementthe rod 53 which is connected with said lever and with the band 'from the drum 48 which w1ll allow the wagon to clrop by gravit The operator again desiring to lower t e wagon to the ground, will grasp the outer end of the ever 56 and throw the same to the right,

looking at Fi 3, and through the connections escribe between the lever 5(Land the band 49 he is enabled to release the band from the drum which will allow the wagon to drop and the drum shaft to operate to unwind the rope or cable therefrom; in this way the operator may allow the 'wagon todeseend just as rapidly possible and to check the movement thereof at any point he may desire, by releasing the lever 56 when the spring 59 will act, in the manner hereinbetore stated .to cause the band 49 to impinge the peripheral face of the drum 48 and lock the gearing against rotation.

I have provided for locking the lever 37 after it is shifted, for the purpose of/causing the clutch parts 30 and 32 to engage for transmitting motion from the shaft 25 to the drum shaft 18. To one of the uprights 3 of the standard 1, preferably the left upright looking at Fig. 1, is secured a plate 61 having the oppositely arranged U shaped portions 62 and 63 as shown. Intothe U shaped portions 62 is adapted to have movement, the up or end of the lever 37 and into the U shaped portions (33 is adapte' to have movement the-lever 56. Operating through the matching walls of the plates 61 is a plunger 64 and one end the-cot isfadapted to be held )IOjECtlllg into the L! shaped portions 62 by means of a coil ,5 tin 65 caring at one end against the w l o the plate 61 and its opposite end against a pin 66 in the plunger 64. In the rear face of the lever 37 is rovided a concave depression or seat 67, w ich, when the lever 37 has been shifted for thepurpose of connecting the clutch parts, will ride over and allow the end of the plunger 64 to engage and seat.

itself in said depression 6? on the leverzand temporarily lock the same in such posltlon, for the purpose of preventing the clutch parts to become accidentally diseii aged through any jar or vibration of the e fplunger, all of which it is believed willfi be understood. Should it'be desired, the rear face of the lever 56 may be provided with a depression similar to that shown at 67 in ism for operating y the lever 3?, and

what longer at .its opposite end, so.thatted by the'operator 'to release" the band 49 from the drum i8,

madein the make-up of the'fritme support and in the detail. construction of the mechancable for which may be fornn also, being made of one piece may bei'fnadc of two distinct parts or 'shouldit be'desirod, a chainfinay be substituted. for the said rope or cable. And the construction of the cross braces or SlllS may be modified as well-.asl

the mannerof detac-habl y connecting thein with the upper ends of the standards.

-(-)ne of the-manyadvantages found in the operation ofmy device is thatthe mechanism on the jack is 'sitively actuated byl'some suitable power or elevating'the wagon, but.

when it-is: desired to lower the wagon the power may be cut 011' andthe we on allowed to drop by 'g'ravity,theopera'tor y means of the clutch controlling the descent of the wagon. This is ofgreat advantage when using. a power pperated by horses as it will horses'for lowering the wagon and the power may,

be seen there is no need to use the stand at rest.

. Having thus fully described myinvention,"

what I"cla1n1 and desire te -secure byLet.
